P3D RE: 65mm versus 75mm lens spacing

["David W. Kesner" <drdave@xxxxxxxxxxxxxxxxxx>]

In photo-3d digest 2970 Greg Wageman says:

>Your reasoning is certainly right for you, and I agree on the model 
>C point in particular (I have the X2B).

Dana was asking for opinions on the different stereobases. I am glad 
you understood that I was only stating MY reasons for choosing the 
model I did. I was NOT trying to say it was the best choice. As Jon 
Golden stated many more people opt for the model B.

Greg, what were your reasons for choosing the model B? What about the 
rest of the RBT owners out there, could you please give us your 
reasons for choosing the model you did?

>But were you being sarcastic about the "commonly available" 
>equipment comment?

No I wasn't being sarcastic, but I wasn't being clear either. What I 
meant to convey is that within this "circle of stereophiles" the most 
common equipment you will find is 41x101 format viewers and 
projectors. If I go to just about any stereo club in the US that is 
the equipment they will have. Yes, they might also have paired 
carousels, but you would probably have to make special arrangements 
to have them at the meeting.

I beleive the same also holds true for individual stereo 
photographers. I just made plans to meet with a few when I am in 
Seattle in two weeks. I just ask if anyone was willing to get 
together and share slides. I didn't mention what format I had and I 
didn't ask what they had. I just assumed that we will all be sharing 
41x101 slides and I'll bet I am right.

I would go so far as to say that if I was doing prints that the "most 
common" method would be side by side Holmes type. Yes, the View Magic 
over/under is commonly available, but once again if I just showed up 
with some prints I'll bet the other party will have a Holmes type 
viewer.

I am NOT saying one is better than the other - just more "common".

> Carousels, Ektagraphics and Pinsharps can be bought new from
> places like B&H and Reel 3D, for example.

Yes, carousels are very common in the "flat world" and Pin Sharps are 
as easy to get as Radex viewers. It is not their availability, but 
ownership and use that I was suggesting.

> Stereo projectors are just about impossible to find outside of our little
> circle of stereophiles, only occasionally surfacing on the 'net.

Why would you look outside our "little circle"? That would be like 
looking for clothing at the grocery store or a Chevy 12 bolt main at 
a Mopar rally. There are plenty of 41x101 viewers and projectors 
available in this circle and there is no reason you shouldn't have 
one if you want one. If you are holding out for a great bargain, then 
you might have to wait a while, otherwise you could have either in a 
matter of days.

>New ones will cost you a mint for a Brackett or RBT.

Just a minute here. Are you saying a $1300.00 ($1085.00 projector and 
$185.00 lens - other lenses more) Brackett is any more expensive than 
two Ektagraphic projectors with matching lenses, polarizing adaptors, 
mounting stand, and synchronizer? OK, you can get the projectors and 
lenses used, and make your own stand, and manually advance each 
projector for less than $500.00.

Now if you want to have two Bracketts for fade/dissolve shows then 
you are starting to talk some bucks. And two RBT's - sell your house!

Thanks for the time,
